either  common  shrapnel  or  common  steel  shell.  The  ammunition  as 
made  up  varies  slightly  in  length  with  the  type  of  projectile  used. 
The  ammunition  chests  of  the  battery  are  of  sufficient  size  to  take 
either  kind  of  ammimition  furnished,  so  that  the  quantity  of  each 
class  of  ammunition  to  be  carried  is  a  matter  to  be  regulated  by 
proper  authority.  All  fixed  ammunition  for  the  3.8-iiich  gun  is 
issued  filled  and  fuzed.  The  weight  of  the  projectile  is  30  poimds 
and  the  total  weight  of  the  fixed  ammimition,  either  shrapnel  or 
shell,  is  37.78  pounds. 

A  cast-iron  shell  has  been  designed  having  the  same  center  of 
gravity  and  exterior  dimensions  as  the  common  steel  shell.  This  is 
used  for  proof  and  range  firing  only* 

THE   CARTRIDGE   CASE. 

[Plate  II.] 

The  cartridge  case  is  a  solid  drawn  case  of  cartridge  brass  having 
a  capacity  of  approximately  142.6  cubic  inches.  The  weight  of  the 
cartridge  case  with  the  llO-graia  percussion  primer  is  4.78  pounds. 

The  base  of  the  cartridge  case  is  stamped  with  the  name  of  the 
gun,  iaitials  of  the  place  of  manufacture,  and  the  year  of  manufacture. 
The  ammunition  lot  number  is  also  stamped  on  the  base  of  the 
cartridge  case.  A  circular  groove  cut  in  the  base  of  the  cartridge  case 
is  painted  yellow  to  indicate  common  shrapnel  and  black  to  indicate 
common  steel  shell,  i.  e.,  high  explosive  shell. 

THE  PROPELLING  CHARGE. 

The  propelling  charge  is  composed  of  nitrocellulose  powder,  the 
granulation  being  cylindrical  and  having  seven  longitudinal  perfora- 
tions. The  weight  of  the  propelling  charge  varies  shghtly  for  differ- 
ent lots  of  powder  and  weighs  approximately  48  ounces. 

Smokeless  powder  must  not  be  used  for  blailk  charges.  For  this 
purpose,  the  Ordnance  Department  furnishes  a  special  powder. 

PROJECTILES. 

COMMON  STEEL  SHELL. 

[Plate  II.] 

The  common  steel  shell  contains  a  bursting  charge  of  3.24  pounds 
of  trinitrotoluol.  Tlie  weight  of  the  shell  with  the  bursting  charge, 
fuze,  and  base  cover  is  30  poimds  with  a  small  tolerance  either  way.

COMMON    SHRAPNEL. 

[Plate  II.] 

The  shrapnel  is  a  base  charged  common  shrapnel  fitted  with  a 
31-second  combination  fuze.  The  shrapnel  filling  is  composed  of 
369  balls,  each  approximately  230  grains  in  weight.  The  balls  are 
approximately  0.54  inch  in  diameter.  The  interstices  contain  a 
smoke-producing  matrix. 

All  shrapnel  ammunition  is  issued  fuzed  all  ready  for  use  and  pro- 
vided with  a  waterproof  hood  over  the  fuze  to  exclude  moisture.

The  action  of  this  fuze  is  similar  to  that  of  the  21 -second  fuze  used 
with  the  3-inch  field  gun.  The  principal  difference  is  in  the  length 
of  the  time  train,  and  graduations  of  the  time-train  ring. 

ALLOWANCE   OF   AMMUNITION. 

Shell  and  shrapnel  ammunition  is  issued  by  the  Ordnance  Depart- 
ment in  moisture-proof  zinc-lined  wooden  packing  boxes,  two  rounds 
per  box. 

The  annual  allowance  of  ammunition  for  the  instruction  of  field 
artillery  is  prescribed  from  time  to  time  in  War  Department  orders.

BLANK   AMMUNITION. 


Blank  metallic  ammunition  consists  of  the  following  components: 
A  brass  cartridge  case,  a  percussion  primer,  a  charge  of  black 
powder,  and  a  tight-fitting  felt  wad. 

THE  CHARGE. 

The  charge  to  be  used  in  the  preparation  of  blank  metallic  ammuni- 
tion for  the  3.8-inch  gun  is  1.75  pounds  of  saluting  powder. 

PREPARATION    OP   BLANK   METALLIC    AMMUNITION. 

Blank  metallic  ammunition  will  be  assembled  at  posts,  the  same 
as  for  3-inch  field  guns,  or  in  the  field  under  the  supervision  of  a 
commissioned  officer,  who  will  be  held  responsible  that  it  is  prepared 
in  the  manner  prescribed. 

FLASH   TARGETS. 

Flash-target  apparatus  is  issued  for  use  with  the  3.8-inch  gun  as 
well  as  other  targets.  For  detailed  information  in  this  connection, 
see  Ordnance  pamphlet  No.  1994. 

3.8-INCH   GUN — DRILL   CARTRIDGE. 

The  drill  cartridge  is  a  dummy  cartridge  for  use  in  drilling  can- 
noneers in  the  service  of  the  gun. 

The  principal  parts  are,  wood  body,  bronze  base,  body  guard,  split 
pin,  graduated  ring,  point  nut,  and  bolt  extending  through  the  entire 
length. 

It  is  the  shape  of  the  service  shrapnel  ammunition  and  is  fitted  at 
the  point  with  a  movable  ring,  graduated  the  same  as  the  ring 
upon  the  F.  A.  31 -second  combination  fuze.  This  arrangement  is 
for  the  instruction  of  the  cannoneers  in  fuze  setting.  No  caliber  .30 
subcaliber  cartridge  is  to  be  used  in  the  3.8-inch  field  gun. 

There  has  been  developed  a  1.457-inch  subcahber  gun  for  use  in 
mobile  guns  and  howitzers  when  fitted  with  its  proper  adaptors. 
This  gun  is  to  fire  a  1.7-pound  smoke  shell. 

THE   HAND   FUZE    SETTER   MODEL   OF    1913. 
[Plate  IV.] 

DESCRIPTION. 

The  fuze  setter  is  a  device  provided  for  the  rapid  and  accurate 
setting  of  fuzes. 

The  hand  fuze  setter  provided  for  the  3.8-inch  gun  consists  princi- 
pally of  an  aluminum  case  having  a  serrated  rim  forming  a  handle 
for  turning;  a  range  ring  mounted  on  the  range-ring  carrier,  which 


15 

is  operated  by  the  knob  on  the  range  worm;  a  corrector  scale  mounted 
on  the  corrector-scale  support,  which  is  operated  by  the  knob  on  the 
corrector  worm,  and  a  guide  plate  which  rests  on  the  projectile. 

A  slot  is  cut  in  the  range-ring  carrier  which  engages  with  the  pin 
on  the  graduated  time-train  ring  of  the  fuze.  A  stop  pin  is  attached 
to  the  corrector-scale  support  and  engages  with  the  stop  pin  of  the 
fuze  to  limit  the  motion  of  the  fuze  setter. 

The  range  worm  and  corrector  worm  are  mounted  eccentrically  in 
the  range -woim  case  and  the  corrector-worm  case.  Upon  rotation 
this  provides  an  adjustment  to  accommodate  slight  variations  in 
machine  operations  and  to  take  up  for  wear  between  the  teeth  of  the 
worms  and  gears. 

The  range-worm  adjusting  screw  and  the  corrector-worm  adjusting 
screw  have  fiber  washers  fitted  in  the  end  which  bear  on  the  collar 
of  the  range  and  corrector  worms  for  taking  up  the  end  motion  and 
to  provide  sufficient  friction  to  resist  accidental  turning. 

Clamp  plugs  are  provided  for  locking  the  range  and  corrector-worm 
cases  and  the  range  Worm  and  corrector  worm  adjusting  screws. 

OPERATION. 

Turn  the  knob  of  the  corrector  worm  until  the  index  on  the  case 
registers  with  the  line  on  the  corrector  scale,  which  indicates  the 
desired  correction  for  height  of  burst. 

To  set  a  fuze,  remove  the  waterproof  cap  and  safety  wire.  Place 
the  hand  fuze  setter  over  the  fuze  and  turn  until  the  slot  in  the  range- 
ring  carrier  engages  with  the  pin  on  the  graduated  time-train  ring  of 
the  fuze;  the  base  plate  and  the  upper  part  of  the  range-ring  carrier 
will  then  bear  firmly  on  the  projectile;  then  turn  the  fuze  setter  in  a 
clockwise  direction  as  indicated  by  the  arrow  on  the  top  of  the  case 
until  the  stop  pin  on  the  corrector-scale  support  engages  with  the 
stop  pin  on  the  fuze,  and  further  motion  is  prevented. 

An  index  to  register  with  a  line  on  the  fuze  to  indicate  when  the 
stop  pin  on  the  fuze  and  fuze  setter  are  in  contact  is  attached  to  the 
corrector  scale. 

HAND   FUZE    SETTER. 

[Plate  IV.] 

OLD   MODEL. 

This  hand  fuze  setter  consists  of  the  following  principal  parts: 
Kange-ring  carrier,  base,  case,  range  ring,  corrector  scale,  plunger, 
plunger  spring,  clamping  shoe,  and  clamp  screw. 

On  the  top  of  the  base  is  mounted  the  range-ring  carrier  to  which 
is  secured  by  four  screws  the  graduated  range  ring.     On  the  interior 


16 

conical  surface  of  the  carrier  is  cut  a  notch,  which  engages  the  fixed 
pin  of  the  graduated  time-train  ring  of  the  fuze. 

The  range- ring  carrier  is  loosely  mounted  on  top  of  the  base  and 
is  held  in  place  by  means  of  the  case  in  such  manner  that  it  can  be 
freely  revolved  so  that  the  desired  relation  between  the  time  train- 
ring  notch  cut  therein  and  the  fixed  plunger  in  the  base  may  be 
readily  obtained  for  the  desired  setting  of  the  fuze. 

In  the  case  which  is  securely  fixed  to  the  base  is  fitted  a  clamp- 
ing screw  and  shoe,  by  means  of  which  the  range-ring  carrier  with  its 
graduated  range  ring  may  be  securely  clamped.  On  the  top  surface 
of  the  case  is  fitted  the  corrector  scale;  this  is  held  in  place  by  two 
screws.  If  after  a  setting  has  been  made  for  a  given  range  it  is  found 
that  the  shrapnel  does  not  burst  at  the  desired  point  in  its  trajectory, 
the  clamping  screw  is  released  and  the  range-ring  carrier  is  revolved 
forward  or  backward  as  desired  until  the  graduation  mark  on  the 
range  ring  comes  opposite  the  proper  graduation  mark  on  the  cor- 
rector scale.  For  making  the  adjustment  for  different  heights  of 
burst,  the  corrector  scale  has  been  graduated  and  fitted  to  the  case  in 
such  manner  that  if  a  lower  point  of  burst  is  desired  the  range  gradua- 
tion on  the  range  ring  should  be  set  to  one  of  the  lesser  graduation 
marks  on  the  corrector  scale,  and  if  a  higher  point  of  burst  is  desired, 
then  the  graduation  on  the  range  ring  should  be  set  to  one  of  the 
higher  graduations  on  the  corrector  scale. 

ADJUSTMENT^ 

As  the  parts  are  adjusted  by  the  manufacturer  before  issue  and 
ample  provision  made  for  lubricating  the  parts  by  filling  the  interior 
of  the  case  with  a  heavy  grease,  there  should  be  but  little  need  for 
adjustment  for  a  long  time. 

Two  oil  holes  closed  by  screws  are  provided  in  the  case  for  emer- 
gency use  only. 

Reference  marks  are  placed  on  the  case  and  worm  cases  to  indicate 
the  normal  adjustment. 

ArrAPTABILITY  TO   OTHER   GUNS. 

This  fuze  setter  is  adaptable  to  all  projectiles  using  the  31-second 
combination  fuze  by  using  suitable  range  ring,  corrector  scale,  guide 
plate,  and  index  bar.  The  corrector  scale  fov  guns  has  60  gradua- 
tions, 30  being  the  normal.  The  range  ring  for  guns  has  but  one 
scale  graduated  thereon.  The  index  bar  for  guns  has  a  fixed  pro- 
jecting arm  on  which  the  index  is  engraved.  The  guide  plates  are 
suitably  marked  for  the  projectile  to  which  they  ^re  fitted.  The 
range  rings  and  corrector  scales  are  marked  wi  t  h  the  name  of  gun.

DESCRIPTION  OF  THE  CARRIAGE. 

[Plates  V,  VI,  and  VII.] 

The  carriage  for  the  3.8-inch  gun  is  of  the  type  known  as  the  long 
recoil,  in  which  the  gun  is  permitted  a  sufficient  length  of  recoil  upon 
the  carriage  to  render  the  latter  stationary  under  firing  stresses. 

As  this  carriage  is  of  the  same  general  design  as  the  3-inch  gun 
carriage,  model  of  1902,  the  description  of  the  carriage  and  its  parts 
given  in  the  handbook  on  3-inch  Gun  Materiel,  Form  No.  1659,  will 
be  used. 

There  are  differences  in  design,  however,  existing  between  some 
parts  of  the  two  carriages,  such  as  in  the  traversing  mechanism,  the 
rocker,  and  other  smaller  parts.  These  are  taken  up  in  their  proper 
order,  and  the  differences  may  be  readily  seen  by  comparison  with 
similar  paragraphs  in  the  above-mentioned  handbook.     Any  dimen- 


24 

sions  given  in  the  description  of  the  3-inch  gun  carriage  will  be  dis- 
regarded, as  the  3.8-inch  gun  has  a  larger  carriage.  Numbers  of 
carriages  will  also  be  disregarded. 

WHEELS. 

The  wheels  are  a  heavier  type  of  the  Archibald  pattern,  58  inches 
in  diameter,  with  4-inch  tires.  The  hub  cap  is  of  forged  steel  and 
no  hub  band  or  hub-latch  plunger  is  used. 

The  wheel  fastening  is  of  a  different  design,  being  made  in  halves 
and  pinned  together  by  means  of  a  pin  and  interlocking  lugs  at  one 
end  and  a  hasp  and  split  pin  at  the  other.  The  fastening  has  a  square 
thread,  onto  which  the  wheel  is  screwed.  The  wheel  is  locked  to  the 
fastening  by  means  of  the  hasp  and  staple. 


The  only  difference  noted  in  the  trail  is  that  the  rear  ends  of  the 
flasks  are  not  flanged  outward  at  the  points  at  which  the  float  is 
attached. 

ELEVATING    GEAR. 

The  functioning  of  the  elevating  gears  is  the  same,  but  differs  in 
construction.  In  place  of  the  angle  the  3.8-inch  gun-carriage  rocker 
has  two  steel  bars  threaded  in  the  pintle  socket  at  one  end  and 
riveted  to  the  traversing  clip  at  the  other.  The  traversing  clip 
serves  as  a  point  of  attachment  for  both  the  traversing  and  elevating 
mechanism. 

TRAVERSING   MECHANISM. 

The  traversing  mechanism  consists  of  the  traversing  worm  shaft, 
mounted  in  a  bearing  in  the  traversing  clip.  The  bearing  is  inclined 
30°  to  the  horizontal  and  is  bushed  at  either  end.  Through  an 
aperture  provided  for  the  purpose  the  worm  thread  on  the  traversing 
worm  shaft  engages  with  the  rack  on  the  traversing  plate,  which  in 
turn  is  riveted  to  the  cradle.  A  pin,  inserted  in  the  traversing  clip 
after  assembly,  serves  as  a  traversing  stop.  Two  small  lugs,  one  at 
the  center  and  one  at  the  right  of  the  traversing  plate,  limit  the 
motion  of  the  gun  to  right  or  left.  The  traversing  worm  shaft 
extends  upward  and  to  the  left,  terminating  in  a  seat  for  the  trav- 
ersing handwheel.  Turning  the  handwheel  causes  the  cradle,  with 
the  gun,  to  be  traversed,  the  amount  of  motion  provided  being  106 
mils,  53  on  each  side  of  the  axis  of  the  carriage. 

CRADLE    COMPLETE. 

The  cradles  complete  are  similar  in  design  and  operation  except 
as  noted.  The  3.8-inch  gun-carriage  cradle  has  three  steel  forgings 
riveted  to  its  under  side — the  pintle,  traversing  plate,  and  cradle-lock 
lug.  The  traversing  and  elevating  mechanism  are  attached  at  the 
same  point.

The  firing  mechanism  is  as  described  in  the  handbook,  Form  1659, 
for  carriages  after  No.  168. 


AMMUNITION   CARRIERS. 


There  are  no  ammunition  carriers  mounted  on  the  3.8-inch  gun 
carriage,  and  all  references  thereto  in  the  handbook.  Form  1659,  should 
be  disregarded. 

ROAD    BRAKE. 

The  spring  cover  and  spring-cover  end  mentioned  in  the  hand- 
book, Form  1659,  are  integral  on  the  3.8-inch  carriage. 

There  is  but  one  rack  riveted  to  the  brake-segment  bracket. 

THE    SHIELD. 

The  apron  is  hinged  to  the  axle-seat  brackets  and  the  axle  bear- 
ings and  reaches  to  within  5.25  inches  of  the  ground.  For  traveling, 
it  is  swung  up  under  the  seats  and  held  by  two  apron  latches,  which 
are  attached  to  brackets  riveted  to  the  foot-rest  supports.  The  main 
shield  is  rigidly  attached  by  bolts  to  the  axle-seat  brackets  and  axle 
bearings  and  is  braced  by  two  shield  braces,  reaching  from  its  upper 
corners  to  the  foot-rest  frame.  It  has  two  wing  nuts  for  securing  the 
top  shield  when  folded  down  and  has  a  sighting  port  and  a  gun  port. 
The  latter  is  made  a  minimum  port,  and  the  shield  is  stiffened  by  a 
hood  riveted  to  its  front  face.  The  upper  edge  of  the  top  shield  is 
64  inches  from  the  ground. 

TO   FILL  THE    RECOIL   CYLINDER. 

In  the  instructions  regarding  the  filling  of  recoil  cyUnders  the  fol- 
lowing important  point  should  be  noted  in  addition  to  the  instruc- 
tions given  in  the  handbook:  Tlie  cylinder  should  he  refilled  after  any 
test  wJiicli  requires  the  retracting  of  the  gun. 

TO   DISMOUNT  THE   TRAVERSING   MECHANISM. 

The  gun  being  dismounted,  reinove  the  traversing  stop  pin  from 
the  chp  and  traverse  the  cradle  (muzzle  end)  to  its  extreme  left 
position.  This  will  disengage  the  rack  from  the  worm  on  the  shaft. 
To  remove  the  worm  shaft,  first  remove  the  handwheel,  next  the  nut 
from  the  upper  end  of  the  shaft,  and  then  unscrew  the  bushing  from 
the  traversing  clip,  which  wiU  allow  the  shaft  to  be  withdrawn.  To 
assemble  the  traversing  mechanism,  the  above  operations  are  re- 
versed. 

TO   REMOVE    A   WHEEL. 

First,  remove  the  hub  cap  by  unscrewing  with  the  spanner  fur- 
nished, remove  the  lock  washer,  undo  and  throw  back  the  hasp 
attached  to  the  wheel  fastening,  and  then  unscrew  the  wheel  from  the 
wheel  fastening,  which  will  aUow  its  being  removed.

TO    REMOVE    A    WHEEL    FASTENING. 

The  wheel  having  been  removed  as  directed  above,  withdraw  the 
0.25  spUt  pin;  the  wheel  fastening,  being  in  halves  and  hinged  at  the 
bottom,  can  then  be  removed  from  the  axle. 

ADJUSTMENT    OF    SIGHTS. 

VERIFICATION    OF   PARALLELISM    OF   LINES    OF   SIGHT   AND   AXIS    OF   BORE. 

information  in  handbook  1659  applies  to  the  3.8-inch  gun,  with 
the  exception  of  that  shown  in  figure  1.

DESCRIPTION   OF   THE   3.8-INCH   GUN   LIMBER,  MODEL   OF   1904. 

The  3.8-inch  gun  limber  is  of  the  same  general  design  as  the  3-inch 
gun  Hmber,  Model  of  1902,  and  therefore  the  description  of  the  latter, 
given  in  handbook  1659,  will  be  used  for  the  3.8-inch  gun  limber. 

The  3.8-inch  has  a  few  differences,  however,  in  the  chest,  the  wheels, 
and  location  of  the  tools,  which  are  described  below. 

The  differences  in  the  wheels  and  the  wheel  fastenings  are  the  same 
as  described  for  the  gun  carriage  in  this  handbook. 

The  chest  door  is  hinged  at  the  top  and  swings  upward  and  to  the 
front.  The  chest  front  and  door  have  not  the  corrugations  men- 
tioned in  handbook  1659,  but  the  door  has  riveted  to  its  inner  face 
tees,  called  bearing  plates,  which  not  only  serve  to  strengthen  the 
door  but  are  so  spaced  that  their  stem  falls  between  the  vertical  rows 
of  cartridges  and  their  flange  rests  against  the  head  of  the  cartridge, 
securing  the  latter  in  position  (when  the  door  is  closed)  and  protect- 
ing the  cartridge  percussion  cap. 

The  door  is  held  closed  by  two  lock  bars  hinged  to  the  bottom  of 
the  chest.  A  hasp  and  two  eccentric  lugs  are  formed  upon  each  of 
these  bars.  In  locking  the  door  the  lugs  come  into  contact  with  its 
lower  edge  pressing  it  forward,  while  the  hasp  engages  a  wing  nut 
on  its  rear  face.  On  the  left  lock  bar  is  riveted  a  chain,  to  the  end 
of  which  is  attached  a  padlock  and  a  bolt  snap.  The  padlock  may  be 
slipped  through  an  eye  in  the  wing  nut,  which  will  lock  the  hasp  in 
position. 

The  capacity  of  this  limber  is  18  cartridges.  The  capacity  of  the 
3-inch  gun  limber  is  39  cartridges. 

The  differences  in  the  location  of  the  tools  are  as  follows: 

The  ax  is  carried  in  brackets  on  the  left  side  of  the  chest 


30 

The  pickax  is  carried  in  brackets  under  the  chest  to  the  k^ft  of  the 
middle  rail,  the  shovel  being  carried  to  the  right  of  the  rail. 

The  hatchet  is  carried  in  two  brackets  riveted  to  the  front  of  the 
chest,  and  the  pole  prop  is  carried  in  brackets  attached  near  the  rear 
edge  of  the  top  plate. 

The  oil  cans  are  carried  in  a  holder  made  of  flange  steel  riveted  to 
the  right  side  of  the  chest. 

No  ammunition  is  carried  in  limbers  used  with  the  gun,  since  the 
weight  would  be  too  great.

DESCRIPTION    OF   THE    3.8-INCH    GUN    CAISSON,  MODEL   OF    1904. 

The  first  three  paragraphs  in  the  description  of  the  3.8-inch  gun 
limber  will  also  apply  to  the  caisson,  the  description  of  the  3-inch 
gun  caisson.  Model  of  1902,  in  handbook  1659  being  used. 

The  following  paragraphs  in  regard  to  the  ammunition  chest  will 
take  the  place  of  the  corresponding  ones  in  handbook  1659: 

The  caisson  ammunition  chest  is  rectangular,  and  is  built  up  of 
flange  steel  formed  to  shape  and  riveted  together  in  a  similar  manfier 
to  that  of  the  limber,  but  is  larger,  having  provision  for  40  rounds 
of  ammunition  arranged  in  4  horizontal  rows  of  10  rounds  each. 
The  front  of  the  chest  is  made  of  armor  plate  0.15  inch  thick.  A 
steel  angle  is  riveted  to  the  armor  plate  all  around  its  edge  and  the 
projecting  leg  of  the  angle,  riveted  to  the  body  of  the  chest.  Three 
steel  tees  placed  vertically  and  riveted  to  the  inside  of  the  front  plate 
give  stiffness  to  the  latter. 

Inside  of  the  chest  the  cartridges  are  supported  by  three  vertical 
diaphragms  flanged  all  around  and  riveted  to  the  body  of  the  chest. 
Each  diaphragm  is  perforated  with  40  flanged  cartridge  holes.  Cor- 
responding holes  in  the  middle  and  rear  diaphragms  are  connected 
by  conical  brass  connecting  pieces  which  are  similar  to  those  used  in 
the  limber  chest.  The  front  and  middle  diaphragms  are  rigidly 
braced  to  each  other  by  two  flanged  steel  braces  riveted  between 
the  two. 

To  the  front  and  middle  diaphragms  are  riveted  vertically  three 
steel  tees  and  to  the  rear  diaphragm  four  steel  tees. 

Nine  instead  of  seven  steel  tees  are  riveted  to  the  inner  face  of  the 
door. 

The  description  of  the  bracket  fuze  setter  and  attachments  in 
handbook  1659  will  be  disregarded,  as  there  is  no  bracket  fuze  setter 
on  this  caisson. 

OTHER    3.8-INCH    GUN    MATERIEL. 

The  following  vehicles  are  also  used  in  the  3.8-inch  batteries: 

The  3.8-inch  gun  forge  limber.  Model  of  1902, 

The  3.8-inch  gun  battery  wagon,  Model  of  1902, 

The  3.8-inch  gun  store  limber.  Model  of  1902,  and 

The  store  wagon.  Model  of  1902. 

The  descriptions  of  these  vehicles  will  be  found  in  handbook  1659 
under  the  following  names : 

The  3.8-inch  gun  forge  limber.  Model  of  1902,  under  the  head  of 
3-inch  gun  and  3.8-inch  howitzer,  forge  limber,  Model  of  1902. 

The  3.8-inch  gun  battery  wagon,  Model  of  1902,  under  the  head  of 
3-inch  gun  battery  wagon.  Model  of  1902. 


34 

The  3.8-inch  gun  store  Ihnber,,  model  of  1902,  under  the  head  of 
3-mch  gun  and  3.8-mch  howitzer  store  hmber,  model  of  1902. 

The  store  wagon,  model  of  1902,  will  be  found  under  the  same 
heading  in  the  handbook. 

On  all  four  vehicles,  however,  the  wheels  are  58  mches  in  diameter 
instead  of  56  inches,  as  given  for  the  3-inch  gun  materiel.  As  the 
hubs  and  wheel  fastenings  on  the  58-inch  wheels  are  of  another  type, 
th^  axles  are  necessarily  different.  In  all  other  respects  these  vehicles 
conform  to  the  descriptions  mentioned  above. 

REPAIRS    FOR    FIELD    ARTILLERY    MATERIEL    ISSUED    TO    THE     UNITED 
STATES    ARMY   AND   THE    NATIONAL    GUARD. 

The  following  is  an  addition  to  the  instructions  found  in  Form  No. 
1659: 

A  small  amount  of  oil  should  be  put  in  each  wheel  before  using,  as 
this  is  the  only  way  to  insure  that  the  wheels  are  properly  lubricated 
unless  they  are  removed. 

After  any  test  that  requires  retracting  the  gun,  the  recoil  cylinder 
should  be  refilled,  since  in  this  position  the  three  holes  in  the  piston 
rod  which  permit  oil  to  flow  from  the  interior  to  the  rod  into  the 
cylinder  when  filUng  are  in  front  of  the  piston-rod  gland,  thus  per- 
mitting some  oil  to  escape. 

METHOD   OF   LOADING   ONE   3.8-INCH   GUN    BATTERY   ON   WAR    FOOTING 
FOR  TRANSPORTATION   BY   RAIL. 

The  flat  cars  usually  obtained  from  railroad  companies  vary  in 
length  from  34  to  44  feet.  Cars  longer  than  42  feet  are  unusual.  It 
is  desirable  that  cars  40  feet  in  length  be  obtained  if  possible. 

In  loading  a  battery  on  cars  during  service  operations  gun  sections 
should  be  kept  together  when  possible.  Pursuing  this  idea,  a  3.8-inch 
gun  battery  may  be  loaded  as  follows  when  cars  at  least  34  feet  in 
length  are  obtained :

One  box  car  is  to  carry  harness  and  all  accessories  of  the  vehicles 
which  are  not  carried  in  the  compartments  of  these  vehicles  or  rigidly 
attached  to  them. 


35 

The  fifth  and  sixth  cars  will  be  only  about  three-fourths  filled  if 
34-foot  cars  are  procured.  The  additional  space  may  be  utilized  as 
the  battery  commander  sees  fit.  • 

If  cars  'ess  than  34  feet  long  are  obtained  one  limber  and  one 
caisson  will  have  to  be  omitted.  If  cars  44  feet  long  are  obtained 
one  additional  limber  or  caisson  can  be  loaded  on  each. 

In  loading  the  cars,  if  there  are  permanent  loading  platforms  along 
the  railroad  tracks  in  the  vicinity,  the  vehicles  should  be  run  onto 
these  platforms  and  loaded  from  them.  If  there  is  no  permanent 
platform  in  the  vicinity  it  will  be  necessary  to  build  a  temporary 
ramp.  This  shoidd  be  built  at  the  side  of  the  track  and  the  vehicles 
run  on  near  one  end  of  the  car.  When  loading  short  cars  it  may  be 
necessary  to  remove  the  pole  of  the  limber  last  loaded  in  order  to 
get  the  limber  onto  the  car.  The  pole  should  be  replaced  in  its 
socket,  however,  as  soon  as  the  vehicle  is  placed  in  position. 

When  loading  the  cars  care  must  be  taken  to  so  load  them  that 
there  can  be  no  movement  of  the  vehicles  on  the  cars  longitudinally, 
transversely,  or  vertically.  All  vehicles,  trails  of  carriages,  poles  of 
limbers,  and  lunettes  of  caissons  and  wagons  must  be  secured  to  the 
floor  of  the  car.     The  vehicles  are  secured  as  follows: 

Two  by  four  inch  timbers  nailed  to  the  floor  of  the  car  on  both  sides 
of  all  wheels  hold  the  wheels  securely  against  transverse  motion. 

Two  by  four  inch  chocks,  nailed  to  the  2  by  4  inch  pieces  which  lie 
along  the  sides  of  the  wheels,  hold  the  wheels  against  longitudinal 
motion.  For  the  end  vehicles  of  each  section  of  three  vehicles  four 
4  by  4  inch  chocks  should  be  used. 

A  2  by  4  inch  crosspiece  placed  on  the  feUoes  between  the  two 
lowest  spokes  of  both  wheels  of  each  vehicle  and  bolted  to  the  floor 
of  the  car  with  two  one-half-inch  bolts  holds  the  wheels  against  ver- 
tical motion.  These  bolts  should,  if  possible,  be  bolted  through  the 
crosspieces  on  the  outside  of  the  wheels.  If  bolts  for  holding  these 
crosspieces  can  not  be  obtained  they  should  be  securely  nailed  down 
with  7  or  8  inch  spikes.  Each  pole  and  lunette  should  be  secured 
to  the  floor  by  nailing  two  2  by  4  inch  blocks  to  the  floor,  one  on  each 
side,  and  one  2  by  4  inch  piece  across  the  top,  near  the  end  of  each 
pole  and  lunette. 

The  trails  should  be  secured  to  the  floor  by  using  four  2  by  4  inch 
blocks,  nailing  one  close  up  in  the  rear,  one  longitudinally  along  each 
side,  and  one  across  their  top  in  the  rear  of  the  trail.  Four  2  by  6 
inch  timbers  brace  the  wheel  hubs  of  the  tw^o  end  vehicles  on  each 
car.  The  hub  ends  should  be  hoUowed  out,  the  lower  ends  being 
spread  well  apart,  forming  lateral  as  well  as  longitudinal  braces  and 
nailed  to  the  floor  of  the  car  and  to  four  cleats  which  are  nailed  to  the 
floor  of  the  car. 

For  carrying  all  harness  and  all  accessories  of  the  vehicles  which 
are  not  carried  in  compartments  of  these  vehicles  or  rigidly  attached 


36 

to  them  one  box  car  should  be  obtained.  The  materiel  in  this  box 
car  should  be  packed  in  boxes  if  on  hand.  In  case  no  box  car  can 
be  obtained  ill  of  the  harness,  etc.,  should  be  packed  in  boxes  and 
placed  on  the  flat  cars  near  the  vehicles.  These  boxes  must  be 
securely  fastened  to  the  floor  of  the  car  to  prevent  them  from  sliding 
off  the  car  or  from  striking  and  injuring  the  vehicles. 

To  load  a  3.8-inch  gun  battery  on  war  footing  will  require  1,150 
linear  feet  of  2  by  4  inch  lumber,  200  linear  feet  of  2  by  6  inch  lumber, 
and  50  linear  feet  of  4  bv  4  inch  lumber.
